Wings

Pushrods Installed ( 3 hrs )

Sect 23-09:  Installed Pushrods between Torq Tubes and Bellcranks for both wings.  (I discovered Vans failed to provide W-730 template used to align bellcranks in neutral position.  When I contacted them, they emailed a dimensioned drawing (and sent the actual one in the mail I plan to use to confirm alignment).  I determined only 1 dimension was critical and some of the shapes were unnecessary - so making the template was relatively easy vs the all the dimensions w/o tolerances shown to .001".... Their engrg dwgs need to be properly dimensioned !

I left fasteners loose to allow final adjustments.   Really like having the Washer Wrenches from Cleaveland Tools...one is shown in pic at inboard rib area near Torq Tube.   These make slipping in small washers much easier - with so much less cussing.
RH Wing...pushrod connected
Very pleased with the silky smooth operation of the control linkages - extra time spent getting the brass bushing fit just right at Bellcranks seems to be paying off.
LH Wing...note fastener not tighted...yet.
